Steel fibers boost concrete strength by 244%, revolutionizing durability standards.
Steel fibers can improve the strength and durability of self-consolidating concrete. Different types and amounts of steel fibers were added to concrete mixes to see how they affected the properties. The addition of steel fibers increased bond strength by 244%, compressive strength by 45%, and flexural strength by 127%. The concrete with steel fibers showed no significant weight loss after freeze-thaw cycles, but the flexural toughness decreased. This study shows that steel fibers can enhance the performance of self-consolidating concrete in terms of strength and durability.
